Hello, my friends. Welcome back to Islander Cravings! Today, I want to share with you the ultimate sunscreen guide for this 2024. Like, I know the summer is already here, and it’s time to soak up the sun and enjoy the great outdoors. But before you do, it’s important to remember the importance of sun protection.
Sunscreen is crucial to any skincare routine, as it helps prevent skin damage and cancer caused by the sun’s harmful rays. In this sunscreen guide, we’ll explore the ins and outs of SPF and the different types of sunscreens available so you can make an informed decision when choosing the right product.
So, how about we dive a little deeper into this sunscreen guide:
What is SPF?
SPF stands for Sun Protection Factor, and it measures a sunscreen’s ability to block UVB rays, the type of radiation that causes sunburn and skin cancer. The higher the SPF rating, the more protection the sunscreen provides. However, it’s important to note that SPF only measures UVB protection, not UVA protection.
Diffence Between UVA vs. UVB Rays
UVA rays are longer and penetrate deeper into the skin, causing premature aging, wrinkles, and skin cancer. UVB rays are shorter and cause sunburn and skin cancer. Choosing a broad-spectrum sunscreen is essential to protect against UVA and UVB rays.

Types of Sunscreens
Physical or Mineral Sunscreens
These contain mineral ingredients, such as zinc oxide or titanium dioxide, that sit on the skin and reflect UV rays.
Pros
- It’s made with natural ingredients that are less likely to irritate the skin.
- It provides immediate protection upon application and is effective against both UVA and UVB rays.
- Additionally, mineral-based sunscreens don’t break down in the sun, providing longer-lasting protection.
Cons
- They can be thicker and leave a white cast on the skin, which can be unflattering for some.

Chemical Sunscreens
These contain organic compounds that absorb UV rays and convert them into heat, preventing them from penetrating your skin. Some common active ingredients in chemical sunscreens include avobenzone, octinoxate, and oxybenzone.
Pros
- They are lightweight and easy to apply, making them a popular choice for everyday use since they don’t leave a white cast on the skin.
- Also, they offer broad-spectrum protection.
Cons
- They can be more irritating to the skin, especially for those with sensitive skin.
- Usually, it takes around 15 minutes to be absorbed into the skin and become activated.
- Some chemical ingredients, such as oxybenzone and octinoxate, have also been linked to potential health concerns. Oxybenzone, in particular, has been shown to disrupt hormones in the body and has been found in breast milk, urine, and blood samples.
- Moreover, these ingredients have been linked to environmental damage, such as coral bleaching.

**Important Note**
While the FDA has deemed these ingredients safe for use in sunscreens, it’s important to be aware of these potential concerns and make an informed decision when choosing a sunscreen. Please read this article and this other one about the proposed order for specific active ingredients found in most chemical sunscreens. If you have any concerns or sensitivities, consider using a mineral-based sunscreen instead.
Okay, now that you know the basics, I hope you find this sunscreen guide valuable and that you keep these resources in mind the next time you are looking for an SPF. Remember, consistent sun protection is vital for maintaining healthy, youthful skin and reducing the risk of skin cancer. So, lather up and enjoy the sun responsibly!
